If you look in the psu forum there should be a sticky there with phaedrus' psu calc. See what it says. I would then account for 10-20% overage. That was why I said the 1000w would be good. With all your components( similar to mine) I am getting 700w usage
Thats all I needed to know. I could care less if its too much for what I have. Im going to be adding another 6970 or 6990 to it here shortly.
If we look at everything in the pc world then everything is too much...Its just like a car, you can get a subaru imprezza, or you can get a subaru imprezza wrx sti. the regular could be just as good for me, but why not secure my self with a little bit more power for when Im going to be needing it?
